Read This Before Upgrading to iPhone iOS 4
August 10th, 2010 MobileFreak
If you have an iPhone 3G, do NOT upgrade to the iOS 4 without reading this first.
Issue:
One of our staff members recently upgraded the OS on his iPhone 3G to the new Apple iOS 4. It was at about that time when her battery began losing power faster than it could be charged. After hours of trial and error, we were finally able to determine that the phone was trying to constantly download email from the MS Exchange server. It was constantly polling the Exchange server even though she had not touched the email settings.
Solution:
Disable the ‘Push’ feature in your mail settings on your iPhone.
For those 3G users who have not upgraded yet, I’d highly recommend you keep the above information handy.

i’d not recommend upgrading to iOS 4 on the 3g, i’ve decided not to even upgrade my 3gs … there’s even a funny parody: http://www.youtube.com/watch?v=Pdk2cJpSXLg
I upgraded 2 weeks ago and had the same problem, but didn’t bother trying to fix it, just went back to previous OS. Maybe I will try again…
This had been a dillema for me before I finally found the solution. For those who are yet to disable the feature yet, I strongly recommend you to disable it as it would save you more than 50% of battery life.
